(showbuz) - Beyonce Knowles' little sister, Solange, has sent a message out to Britney Spears' pregnant little sister, Jamie Lynn - urging her to do "what's best".
Knowles, who gave birth to son Daniel in 2004 at the age of 18 and split with husband, former college football player Daniel Smith, after the baby was born, said: "I'm sure a lot of people perceived that I was gonna be a young, irresponsible mom."
But Knowles, now 21, pointed out, "I think that there are some moms who are 35 who are just as irresponsible."
And her advice for 17-year-old Jamie Lynn is that, "You just have to make the best decisions for you," Knowles said. "You have to decide what's best for you.
"Who are we to say what's right and wrong for a person?"
To focus on raising her son, Knowles said she "moved to the country for a year" without any nannies or babysitters.
"My parents lived on a whole opposite part of the world," she said. "My son has been my focus ever since the day he was born."
"He's been the light of my life," she added to Us Weekly, "the inspiration behind everything."
